Low Tech Gutenberg?
Peace Corps Guy asks: "I have a friend who recently left for a two year Peace Corps stint in Mozambique. While there she has limited access to electricity, no technology, and not a lot to do with her 'off' time. She's a big literature fan, and many of us here at home would like to send a care package - but how best to ship pieces of free online text like Project Gutenberg to a developing nation? We can print it (high shipping and printing costs), print it very small and ship her a high quality fresnel lens (awkward), or put it all on a cheap PDA, which would be a high theft risk en route and in situ. High shipping costs on weight and volume are another major limiting factor. What alternative solutions can Slashdot readers suggest for shipping a freely available byte-stream to someone without a computer?"
You've got the right idea, but let me build on it. A relatively new development you may not have heard of has been created by some industrious Germans several centuries ago. This new method of presenting byte-streams is highly affordable, portable, and contains an embedded reader which does not require an external source of energy. While the initial selection of material was limited, I understand that the idea of the Gutenburg press has taken off to some extent in the following centuries, meaning that you should be able to ship any number of Dungeons and Dragons paperbacks to your friend.
